Optical Coherence Tomography Noise Reduction Using Anisotropic Local Bivariate Gaussian Mixture Prior in 3D Complex Wavelet Domain

Figure 18

(a–d) show denoising results for Confocal Microscopy Phantom: from left to right: noise-free image, noisy image, and denoised image with our model and denoised image with Fast TI Haar algorithm. (e–h) show from left to right parts of denoised Barbara image with BiGaussMixShrinkL method and parts of denoised Barbara image with Fast TI Haar algorithm.
